CONVERSION OF SKINS INTO HORNY IVIATERIAL.

SPECIFICATION forming part of Letters Patent No. 579,000, dated March 16, 189'}. Application filed May 11,1896. Serial No. 591,147. (Specimens.) Patented in England January 25, 1895, No. 1,820.

translucent, suitable for making buttons,

busks, handles, boxes, gear-cases, golf-balls, insulating material, and other articles.

For this purpose the skins are subjected to the action of lime-baths, and are cleared in the usual way from the hair and the fleshy matter. The skins are then again subjected to a lime-bath, and afterward are soaked in water until the pores are freed from lime, after which they are thoroughly dried, preferably in warm chambers. The dried skins are then immersed for a short time in heated oil, such as linseed-oil or other vegetable oils,

or oleaginous matter, such as Vaseline or mix tures of such materials. When the product is desired to be somewhat soft and elastic suitable for .busks or bones for corsets and the like, the temperature of the oleaginous material in which the skin is soaked should not exceed 250 Fahrenheit. When a compact hard material is required, the temperature 3 5 should be higher, up to the boiling-point of the oleaginous bath. In either case an immersion for a few minutes is sufficient, after which the material is pressed, so as to squeeze out surplus oil and flatten the converted skins, 4o producing: them in the form of plates or slabs.

Having thus described the nature of my invention, and in what manner the same is to be performed, I claim The process of converting skins into mate- 45 rial of a horny character, consisting in heating the same (after the conclusion of the bathing and drying processes), in oil or similar material at a temperature of about 250 Fah renheit, or above, whereby the albulninous or 50 similar substances are changed to a horny character; substantially as described.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 22d day of 55 April, A. D. 1896.
